unknown frame

I just got this last night. The guy I got it from said he received it in the condition you see in the pictures. It kind of looks like an old Speedway to me. I had one years ago and this one has a few similarities. The forks, spine, the seat pan (what's left of it), and the swing arm. The bike...

Does anyone know what mini bike this is??? I want to find an original picture so I can put it back together. It has some odd front shocks, I think it might have a crossover for the chain. It has a spot for a headlight and I think a tail light.

Hey all, First timer here but I did dig through the feed and have not found this actual frame. I would like to attempt a period correct'ish revival for this killer old crawler. I'm open to any opinions here and I'm willing to track down all leads. Later,
